As you point your hand at your target you release a chilling purple ray.

A purple ray springs from your hand, drawing power from the void, giving you the power to wrack one target with an unnatural chill. You must succeed at a ranged touch attack to strike the target. The target takes 1d4 points of cold damage per caster level (maximum 15d4); there is no save for this part of the spell. The target creature also takes 2 points of Constitution damage unless it makes a successful fortitude saving throw.
